HARRY T. SCOTT, AND LEO a.- PATTERSON, or Los' ANGELEsOALIFoRNIAg SAIVD `:PATTERSON ASSIGNOR To SAID SOOTT,

To all whom it may concern: l A y Be it known that we,.HARRY T SCOTT and LEO J. PATTERsoNf, citizens offthe 4 United States, residingv at Los Angeles, 1n the county of Los Angeles, State of California, have invented new and useful Improvements in Automatic Phonographs, of which the following is a specification. 'y

vThis invention relates to improvements in our-former devices, set forth in our applications Serial Nos. 605,881 and 629,892, tiled ,February 1st, 1911 and May 27th, 1911, re.- spectively/,tnd particularly to a novel mode of securing the motion of the record carrying mandrel. i

Whereas in bot-h our former invent-ions mandrel shaft, with various appurtenances for controlling this feed, in the present ma chine We provide for feeding the'mandrel. shaft by diderential kscrew action on the shaft itself. As will be seen from the, followingspeciiication, the mechanism for aof complishing this feeding action is very simple in its elements and combination, and each of the elements is of vsuch vdesign that the machine is less liable to wear, particu'- larly having no small wearing parts. i Inthe invention as now constitutedA there vertical bearings so as to he rotatable and long gitndmallyv translatable, a suitable screw thread'being cut on the outside of the mandlrel shaft. A rotatable nut engages with the shaft thread so that, by rotation of this nut, .the shaft may be either raised or lowered, according to the direction O-frotat'ion. Means are provided; for rotating the nut and the shaft at differential speeds, and for stopping and starting the rotation of the nut andl shaft at different points in the operation of the machine. The direction of the mandrel screw thread in the present machine is such that, to feed the mandrel shaft downwardly by the differential action, the nut must be rotated slightly faster than the shaft itself; but it will be seen that, by suit-able arrangements, this di fcrential action might be eX- ple gearmeclianism is provided connecting the nut with a sleeve rotating about the ,Specification ofv Letters Patent.

shaft and is rotatably connect-ible to the shaft through the means of another sleeve loosely keyed to the shaftand slidable there on, the two sleeves having co engaging means which may be slid into or out of en; gagement. The gears connect the first-mentioned sleeve with the nut in such manner rection; so that it. will be seen that.` if the. arrangement is such that when the nut alone is revolving the shaft is moved downwardly,

when the shaftalone revolves in the same direction it will .-be moved upwardly. The rate of these movements will depend entirely upon the speed of rotation of the nut and shaft and the pitch of the screw thread; and the pitchis made Suiiiciently coarse to cause the movement of the-shaft at. a comparatively high speed when either the nut or the shaft is rotated alone. But when the nut and shaft are rotated together, the differential actionv causes the slow downward movement of the shaft while itjis rotated; and itis during this movement that the reproducing mechanism is thrown into engagement with the record. to follow its sound groove. Thus, considered in a broad manner. the operation of Athe device is as follows: Mechanism controlled by the shaft when in its lowermost position causes the shaft to begin rotating. This immediately screws the shaft upwardly 'until it reaches its uppermost position. Mechanism cont-rolled by the position of the shaftatits uppermost point causes the nut to begin revolving and the' also provided Afor automatically feeding the record carrying table and for'moving the l reproducer into and out of engagement with .a record; hut these `means donot enter broadly into the combination, entering only' specitically'when the mechanical details are considered.

1n the drawings 5 designates al suitable 'case having a cover 6 beneath which record carrying table' 7 is mounted, record 8 being placed in pocket 9 as in the.- devices of the l former applications above referred to. This *record carrying table ismounted on anilpright table shaft 1.0 which is mounted Vin bearings 11 and12 in main'frame13 of the'- machine. Frame 13 is of the.l general rectangular form' illustrated `in Fig. 2 and is -secured to the casev 5 in any 'suitableman- I ner.. vShaft 10 is so mounted that it is freely `the machine. Mandrel v17 is -mounted on the upper end of mandrel shaft 18 'mounted in bearings 19 and 20- inframe-13. .Thisl man- ,aldrelshaft is revoluble Vand vertically movable along its longitudinal vertical axis and is-provided with a screw thread 21 throii'gh- Iout a considerable portion of its lengt-h. It

also is .provided with a key-way 22.

Mounted around i mandrel shaft 18 and i, situated in a bearing 25 in the lower part of frame 13 is a fly-wheel 26. This fly-Wheel is driven by any suitable means, such, as a "belt 27 from a small motor 28 mounted on a 1 heavy frame 29 which extends across the,y case andjlis'of. such weight. as to efficiently absorb anyof the. motor vibrations and thus reduce' to a minimum v'all noise within'the case. Flywheel 26 has nod-ireet rotational sleeve 30 rotating alone.

merely placed around the shaft on account of the convenience of this location. Situated directly above the fly-wheel 26 is a sleeve 307 loosely engaging vthe shaft and having gear teeth 31 thereon. This sleeve 30 is driven through the medium of an arm 32 which engages a notch 33a'in the ffy-wheel,

the sleeve and gear teeth being thus driven directly with the iiy-wheel. This sleeve has no direct rotational t connection with the shaft, its connection with the shaft being through the medium of another sleeve 33 provided with a kev 34 which engages in key-way 22 of mandrel shaft 18, thevv two sleeves being provided with co-.engaging means 35 causing the revolution of sleeve 33 from sleeve 30. In the position shown in the drawings sleeve 33 is shown in its upper position so that it does not engage at all- ;With sleeve 30. In this position the sleeve 33 andthe mandrel shaft will not be rotated, y The means for raising sleeve33 and forallovving it to drop into engagement with sleeve 30 will be hereiriafter explained. r

Located alongside -.mandrel shaft 18 is a counter shaft 40 mounted in suitable bearings 41 and 42. This shaft is both rotatableand slidable and carrieson its lower'end a gear 43 which engages with gear teeth 31- of sleeve 30 when gear 43 is in its upper position; but when-the Agear 43 is moved down- V-vvardly it will move out of' engagement with gear teeth 31 andthe rotation of gear 43 arid shaft 40 will cease. Directly above bearing 41 a large and small gear 45 afnd`46 are mounted together on a sleeve 47 loosely mounted on1 shaft 40. Gear 45 also meshes with teeth 31 offsleeve 30 and gear 46 drives a vgear 48 which is a. portion of the meehanism for automatically feeding the record carrying table. This mechanismv will -be later explained. Above bearing 42 of shaft 40 another. gear ,50 is mounted in an independent 'bearing 51.. Gear 50 is'not of the same diameter and number of teeth as. gear 43, being, in this case, of slightly larger diameter and having'A -a larger number of teeth. This gearQ meshes with gear teeth 5,22 on nutv 53; and the diameter of teeth 52 being the same as Athat of teeth 31, it follows that the center of gear 50 will be slightly .farther from the center' of. mandrel shaft- 18 than is the center of gear l43'. Thus, asl lgear 43 is'directly mounted on shaft 40, the

center of gear 50 'must be set slightly eccen.

tric 'to the centerof shaft`401 and this is most -conveniently done by providing the gear 50 with an independent bearing.'v The driving means provided between' the gear 50 and the shaft 40` are 4shown particularly in Figs. 3.and 8. A disk 55 lis'slidably keyed 'to shaft (.soas to allow the longitudinal l movement of ,the shaft, as will be hereinconnection with mandrel lshaft 18; is.

after' explained) and this' disk is provided e watch back out of engagement with colvby means of a catch 70 which engages! over with a slot and a hole 56 and 57 and with which pins 58 engage, the pins being rigidly mounted on gear 50. The slot 56 and hole 57 provide accommodation for the eccentric movement of 'the gear and the disk while they alsoprovide for the driving of the gear from the disk in a practically uniform manv ner. lt will be understood that this arrangement is only one of several possible arralngements for obtaining a differential drive between sleeve 30 and nut 53. In the\present instance, it is desired during the differential movement of theshaft to 'move it downwardly TIT of an inch for each revolution. The screw thread 21 in the shaft has a onehalf inch pitch, so that nut 53 is necessarily rotated film times faster than sleeve 30 and shaft-18. If the pitch of the thread in the mandrel shaft be changed, then the differential speed between the sleeve and nut may be changed.l This differential speed rests entirely on the proportioning of the connectv ing gears; and it is conceivable that the sizes of the four different gears might be` so arranged with suitable numbers of teeth` so that gear 50 could be directly mounted on, shaft 40. AIn this case it would probably be diflicult to obtain a differential speed of, Tg but, taking for instance that a differen-v tial speed of could be easily obtained, the screw thread in the mandrel shaft could: be so pitched thatthe shaft would be moved: downwardly el@ of an inch for each revo, lation thereof. It is only on account ofl convenience as to size of gears and as'to` pitch of the screw thread-that the present arrangement is adopted.

The means for sliding the vcounter shaft 40 is comprised in al leverage mechanism arranged above frame 13 andy operated-by a collar 60 secured on the mandrel shaft immediately below record mandrel 17. Collar 60 on reaching the position shown in the drawings contacts with lever 61 which is? pivoted at 62 tothefframe. Lever 61E-'s' normally supported in the position shown. by a spring 63. The upper end of shaft 4071 j is pivot-ally connected at 64 to lever 61 so"v that, when the lever is moved downwardly', the shaft will be moved downwardly to move. gear 43 out of engagement with gear teeth';=. 31. `NVhen this`movement has been accointends downwardly as is shownin Fig. 2 and is connected by an adjustable connecting' arm 79 having a memberl 80 on its end with which a collar 81 mounted on the lower end of mandrel shaft 18 is adapted to engage when the mandrel shaftis in its uppermost position. When the mandrel shaft reaches this uppermost position this collar 81 engages with member and pushes it away from the shaft in the direction indicated' in Fig. 7. This rotates arm 77; and-moves connecting rod 76 longitudinally, causing the movement of lever -75 in the direction indicated in Figs. 2 and 3. This causes the withdrawal lof `catch 70 and allows shaft 40 and gear 43 to-move upwardly *under the impulse of spring 63. This again places gear 43 in engagement with -gea'r teeth 31 of sleeve 30..

As before explained, gear 48 is. driven from gear 46, gear 46 being of sufficient width to mesh with gear 48 when the gear 48 is raised from the 'position shown through a distance about equal to its own width. `Gear 48 is lo-osely mounted on a slidable shaft between twocollars 91, so that the y gear may revolve on the shaft andv may be 'raised and lowered by moving the shaft vertically. This shaft is mounted in suitable bearings 92 and is raised by the mechanism about to be described, being lowered by its own weight. A yoke 93 is attached to the lower end of shaft 90, this /yoke being of liy-wheel 26, and the lower end of the yoke is again attached to a rod 94 which passes downwardly to the lowerpart of the plished, the lever 61 is held in its lowermost upper face of gear 48 and' is adapted to -be position against the pressure of spring 63 the upper sur-face of a collar 71 on a rod 72 attached to the end of lever 61. Catch 70 is formed on the end of a sliding 'rod- 73 pressed by4 a spring 74 into engagement with rod 72 and collar 71. A lever 7.5 pivoted at 76 to frame 13 provides 'means for pulling Ear 71 and 'for allowing spring 63 to then nieve leiler61 and shaft/40 upwardly to the 'moved in the direction indicated in Fig. 4 when engaged by the driving pin 100. lThe ratchet arm can on'ly be `engaged by the pin when the gear'48 is in its uppermost position, for whenthe 'gear 48 is lowered the arm. The ratchet arm is hinged at 102'so that its end may rise' when pin 100 should happen to be raised directly under the end of the arm. thus obviating any liability of breakage of `any parts.

The means for registering 'the table exactly in .pction after it hasben fed through an a Jropriate portion offa' revolution is sh'own' particularly in Fig.- 6.

The-spring pressed ball is mounted in the-end of a tube 112 and a spring 113 forces it .resiliently into engagement with the apertures. Then the table is fed, the

engagement of the ball with an aperture is suiicient to stop the table exactly in. position; while the resistance imposed is easily overcome by the force withwhich the ratchet mechanism operates.

On ratchet arm 101 there is arranged a i shoulder120 which engages with a lug 121 that indicated by a spring 124.

on a small frame 122 just as the ratchet arm passesthrough the last portion of its movement and just as the table is cominginto its correct position. This' causes" the frame 1122, to move in the direction indicatedin Fig. 4 and causes af rod 123 to move in thefsame direction, Vthis rod being attached to the frame 122. Rod 123 is nor- -mally pressed infthe ydirect-ion opposite to A yoke member 125 serves to, pass the connection of rod, 123 around the counter shaft 40 and rod 123a practically forms Ia continuation of rod '123, on the other side of the counter shaft.

The'end of this rod 123a engages with a spiralvgroove 126 in the periphery of sleeve 33.- This groove 126 is so made that when rod 5123aL is allowed to be spring prested against thesleeve 33, the end or" the rod will drop into the spiral groove and the rotation of the sl'eeve will then canse thesleeve to rise and to disengage the coengagingmeans l and thusto-sev'er ,its

Rod 123 ispre- .vented from moving inthe direction oppo- 60 'allow ends 123a-toengage .with the spiral groove 126, by means of. two detents 130 site to' that indicated, in' the direction to and 131 engaging withndtches 132 and '1.33, grespectively.` DetentI 131 is formed on the fiend pf a; rod 134 which isflooselyjconnected vshaft 90 and gear 48.

through a slot and pin 135 and 136 with lever 61, so that, when lever 61 is in its lower position, the detcnt 131 may drop into notch 133 when thenotch passes under the detent. Detent 130 is formed on the 'upper' end of a rod 137 which is normally pressed upwardly by a spring 13S, so that detent 130 will engage notch 132 whenever notch 132 passes yabove it. The lower end of rod .137 is connected to the end of a lever 139 pivoted at 140 to the under side of frame 13 and having a depending portion 139a whose lower end is adapted to be engaged by collar 81 when the collar reaches the position shown in dotted lines in Fig. 2. The outward movement of end 139n of the lever causes the downward movelnent of the end connected to rod 137 and pulls the rod downwardly against the pressure of -spring 13S and releases detent 130 from notch 132. A

Having described in the main the mechafnism lof the present machine, we will now yproceed to describe its operation, adding the description of the few remaining parts as the description of the operation progresses. Start-ing with the mandrel shaft 'in the position shown, and moving downwardly, it will be seen that lever 61 will first be pressed downwardly, moving` shaft 40 downwardly and moving gear 4-3 out of engagement with gear teeth 31. This will 'immediately stop the rotation of shaft l0 and will therefore stop the rotation of nut 53. Nut 53 has spiral ribs 53 which engage with the screw thread of the shaft and 7the continued rotation of the shaft will cause its movement when the nut is stationary. But, with the machine in the position shown, the shaft is not rotated, the sleeve 33 having been raised out of engagement with the sleeve 30. Consequently, as soon as gear 43 is disengaged from gear teeth 31, the mandrel shaft will cease its downward motion. At the same time, when coming to its lowermost position, the lower end of the shaft engages with the end 9S of lever 96 and causes the upward movement of This causes feed pin 100 to come into contact with ratchet arm 101 which immediately causes the rotation of the record carrying table through, in this case, 11g of a revolution. -Just as the table comes to its final position, the rod 123 is drawn in thrpdirection indicated in the manner hereinbefore explained. Arm 6l being in its lowermost position` deteut 131 is allowed to drop into notch 133 and detent 130 is also forced up into notch 132 h v the act-ion of its spring 13S. Rod 123 is thus withdrawn from sleeve 33 and the sleeve allowed to drop and to engage with sleeve 30 which is constantly rotated. This immediately starts the rotation of shaft 1S;

, Aso D lower end of shaft 16H m its lowermost position, being held in this posit-ion by the engagement of detent 70 with collar 71. The rotation of shaft 18 in the direction indicated thus causes thequicl: upward movement of the shaft., When the shaft reaches its uppermost position the detent 70 is withdrawn from collar 71 and the lever 61 is allowed to be moved upwardly under the pressure of spring 63. This immediately moves the gear 43 up into engagement with gear teeth 31, thus starting the rotation of vnut 53. Nut 53 is rotated slightly faster than the shaft, so that the shaft is immediately fed downwardly by the differential action. At the same time the reproducer is let into engagement with the record carried by the mandrel 17 by a means which will behereinafter explained- When the mandrel has moved downwardly through a distance corresponding to the length of the sound groove portion of the record, and has carried all of the soundy groove past the reproducing point of t-he reproducing mechanism, then the collar 8l on the lower end of the shaft engages with the end 1391 of Vlever 139 and causes the withdrawal of detent 130 from notch 132. Detent 131 having been previously withdrawn byv the upward motion of lever 61, the rod 123a is allowed to move into engagen ment with spiral groove 126 and the rota-'- tion of sleeve then immediately raises itv to' the position shown in Fig. 3. The nut 53 continues to revolve and thus to force the shaft 18 downwardlyl until it reaches thel position shown in Fig. 3, when the whole above described 4operation is repeated. The utility of detent 131 is this, that, on theupward movement of the mandrel shaft, the collar 81 will engage with the end 139A of lever 139 and will pull detent 130 out of engagement A with its notch 132 but it isnot desired to allow rod l123a to enter the spiral groove 126at` that time; .and lever 61 being in its lowermost position while the shaft is -Inoving` upwardly, the detent 131 will then prevent the movement vof rod 123a into the` spiral groove. Detent 130 will immediately move back into its notch 132 when the collar 81 has passed the lever endp139a and will vhold -the rod 123a from movement into the spiral' Groove when detent` 131 is Awithdrawn by the upward movement of lever 61' when .the shaft reaches its uppermost position. i i The means for moving the reproducing Lmechanism is comprised in a spring 'y 150;

jwhich tends ,to rotate shaft 16 in the direc'-l tion indicatedand in a ymeans for holding the shaft from rotation in that direction eX cept at the timesl .when desired.V To the s lattached an army, 151 whose end engag "ith acollar 152o`1'rz-- sleeve 33 and havinga conical uupper sur,

and causes the rotation of shaft 16 in the direction opposite to 4that indicated; Sleeve v33V movesupwardly immediately a record has completely passed by the reproducing mechanism,jandiso,v by this movement the reproducing mechanism isA movedaway from the record immediately the record has been; completely reproduced; but the sleeve 33 moves downwardly again when the mandrel shaft reaches its lowermost position, and it is not desired to nove the,l reproducing mechanism into engagement with the record luntil the record has been completely raised to its uppermost position; in other words, until themandrel shaft has again reached its uppermost position. This is Vaccomplished by means of a collar 155-on shaft 40 .which engages with an arm 156 also ,mounty ed on the lower end of reproducer shaft 16 and holds the reproducer shaftfagainstrotation in the direction .indicated until shaft 40 moves upwardly when the mandrelshaft reaches the uppermost end of -its stroke. Shaft 40 moves` downwardly upon mandrel shaft 18 reaching its-lowermost position; while sleeve 33 does not move upwardly un- -til the mandrel shaft has reached its .lower- Amost position and the feeding operation has completely taken place. Consequently, collar 155 will catch arm 156 and hold it in the position shown in Fig. 3 before sleeve 33- moves downwardly and allows arm 151 to move inwardly. ,The reproducer shaftvwill thus be held fromrotation in the direction indicated from the ,time the record has been completelyplayed till the time another record has beenV raised toits uppermost position .ready for reproduction.

In Figs. 2 and 34 we have shown a means comprised in .an-oil vdistributingv pipe or tube 200 into whichy oili'shcompressed` 'by a small pump 201`arrangedfwith a foot-piece 202 adapted to be'*y lressecl downwardly by the lower'end of s aft 18 orby 'collar 81 110 when the shaftrea'ches litslowermost position.
